My plan is to maintain NC like I have been doing. My bosses and I are having a face to face meeting with her boss next week. My boss actually knows EVERYTHING about this girl. I mean EVERYTHING. I told him when we broke up because I knew there was a strong chance something like this would come up. In regards to the harassment complaint, I never harassed her so she can't possible have any type of legit proof that I did.
It sounds like a distortion campaign from your ex.
